Neither Bartomeu nor Barcelona have yet commented on the resignations.

"We have arrived at this point because we cannot reverse the way the club is managed in the face of important challenges in the future, especially in the post-pandemic era," the six said in their letter.

"We also want to show our displeasure over the unfortunate episode about the social media accounts, known as 'Barcagate', which we learned about through the press.

"As our last act of service to the club, we recommend that elections are called as soon as circumstances permit so that the club can be managed in the best way possible and deal with the important challenges of the immediate future."

Barcelona players will take a 70% pay cut during the coronavirus pandemic and make additional contributions to ensure non-sporting staff receive full wages.

Barcelona's board of directors, members of its professional sports teams and most of the basketball team have also agreed to reduce their salaries.
